This is more difficult than it sounds, since our senses and brains are evolved to provide us with a finely synchronised and mediated experience. If anything is even a little off we can usually tell. This is where you’ll hear terms such as immersiveness and realism enter the conversation. These issues that divide convincing or enjoyable virtual reality experiences from jarring or unpleasant ones are partly technical and partly conceptual. Virtual reality technology needs to take our physiology into account. For example, the human visual field does not look like a video frame. We have (more or less) 180 degrees of vision and although you are not always consciously aware of your peripheral vision, if it were gone you’d notice. Similarly when what your eyes and the vestibular system in your ears tell you are in conflict it can cause motion sickness. Which is what happens to some people on boats or when they read while in a car.
It's not without issues though. We've already discussed VR exercise equipment as a promising concept let down by being such an expensive, bulky and sweaty process. But if you really want to "get in" the game, and you have space, hopping into an Omni could be pretty neat. We've tried it since its early days at CES and it's been able to stick it out through the years, improving the base, harness and shoes to ensure the best possible experience. https://www.aliexpress.com/item/Homdox-360-Degree-Adjustable-Foldable-Laptop-Stand-Notebook-Computer-Desk/32727071992.html
Standalone headsets were at first a useful novelty that offered a taste of VR without an investment into a gaming PC or a flagship phone. The Oculus Go and the Lenovo Mirage Solo are both capable headsets that work well on their own, but they have the same limited controls as mobile headsets. The recently released Oculus Quest, however, has really sold us on this category. The Quest uses similar outward-facing cameras to the new Rift S to provide 6DOF motion tracking, and uses the same Oculus Touch motion controls. Combined with a faster Snapdragon 835 processor compared with the Oculus Go's Snapdragon 821, the Quest offers a much more compelling and immersive VR experience, all without the unwieldy cable or PC requirement of the Rift S. We hope to see more standalone 6DOF, dual motion controller headsets in the future, like the upcoming HTC Vive Focus Plus. https://www.youtube.com/watch?v=hmnkcP-sJHk&t=1s
To fully experience PC games and other software in 3D, you'll need a player or computer that is capable of delivering high-quality graphics to a virtual reality headset. This requires a player or computer with a powerful graphics card and processor. It's also recommended that your computer have at least 8GB of RAM in order to download VR content. The number of VR-ready PCs continues to grow, so you'll have a variety of options to choose from in order to enjoy smooth gameplay, even when running graphics-heavy games. https://www.youtube.com/watch?v=vbkvB-kljEo&t=1s
Microsoft HoloLens is shaping up to be another formidable competitor in the HMD market. Unlike VR tech, Microsoft based their display on holographic technology. The original Hololens was more proof of concept than consumer device, and the recently announced Hololens 2 is again eschewing the public in favor of enterprise/government uses. The Hololens 2 will feature upgraded visuals, including a much-expanded field of view — music to fans of the original device, who settled on the limited FOV as the main drawback of the device. https://www.youtube.com/watch?v=UlQt4HNIFXE&t=1s
In 2010, Palmer Luckey designed the first prototype of the Oculus Rift. This prototype, built on a shell of another virtual reality headset, was only capable of rotational tracking. However, it boasted a 90-degree field of vision that was previously unseen in the consumer market at the time. Distortion issues arising from the lens used to create the field of vision were corrected for by software written by John Carmack for a version of Doom 3. This initial design would later serve as a basis from which the later designs came. In 2012, the Rift is presented for the first time at the E3 gaming trade show by Carmack. In 2014, Facebook purchased Oculus VR for what at the time was stated as $2 billion but later revealed that the more accurate figure was $3 billion. This purchase occurred after the first development kits ordered through Oculus' 2012 Kickstarter had shipped in 2013 but before the shipping of their second development kits in 2014. Zenimax, Carmack's former employer, sued Oculus and Facebook for taking company secrets to Facebook; the verdict was in favour of Zenimax, settled out of court later.
Answering “what is virtual reality” in technical terms is straight-forward. Virtual reality is the term used to describe a three-dimensional, computer generated environment which can be explored and interacted with by a person. That person becomes part of this virtual world or is immersed within this environment and whilst there, is able to manipulate objects or perform a series of actions. https://www.youtube.com/watch?v=kU6i_HEKJgg&t=1s
According to CEO Stanislas Chesnais, the 3DRudder was designed for "existing games where two hands aren't enough [for] VR, where you don't actually have any solutions today to move in a nice way while sitting." A circular device that you control with both feet by tilting in the direction you want to move, the 3DRudder's latency-free design means that response to your movements is instant and requires little thought. "It's like in real life," says Chesnais. "When you do something [like] set the table… you don't think about your feet moving around. Your hands are what matter." https://www.youtube.com/watch?v=LD4XfM2TZ2k&t=1s
A head-mounted display (HMD) more fully immerses the user in a virtual world. A virtual reality headset typically includes two small high resolution OLED or LCD monitors which provide separate images for each eye for stereoscopic graphics rendering a 3D virtual world, a binaural audio system, positional and rotational real-time head tracking for six degrees of movement. Options include motion controls with haptic feedback for physically interacting within the virtual world in a intuitive way with little to no abstraction and an omnidirectional treadmill for more freedom of physical movement allowing the user to perform locomotive motion in any direction. https://www.aliexpress.com/item/Insta360-PRO-8-K-360-VR-Kamera-Video-4-K-100fps-Gerakan-Lambat-Anti-Shake-Kamera/32832297122.html
Unsurprisingly, the video games industry is one of the largest proponents of Virtual Reality. Support for the Oculus Rift headsets has already been jerry-rigged into games like Skyrim and Grand Theft Auto, but newer games like Elite: Dangerous come with headset support built right in. Many tried-and-true user interface metaphors in gaming have to be adjusted for VR (after all, who wants to have to pick items out of a menu that takes up your entire field of vision?), but the industry has been quick to adapt as the hardware for true Virtual Reality gaming has become more widely available. https://www.youtube.com/watch?v=1bhq5-eXuVQ&t=1s
In 2001, SAS Cube (SAS3) became the first PC-based cubic room, developed by Z-A Production (Maurice Benayoun, David Nahon), Barco, and Clarté. It was installed in Laval, France. The SAS3 library gave birth to Virtools VRPack. In 2007, Google introduced Street View, a service that shows panoramic views of an increasing number of worldwide positions such as roads, indoor buildings and rural areas. It also features a stereoscopic 3D mode, introduced in 2010.
Convincing Virtual Reality applications require more than just graphics. Both hearing and vision are central to a person’s sense of space. In fact, human beings react more quickly to audio cues than to visual cues. In order to create truly immersive Virtual Reality experiences, accurate environmental sounds and spatial characteristics are a must. These lend a powerful sense of presence to a virtual world. To experience the binaural audio details that go into a Virtual Reality experience, put on some headphones and tinker with this audio infographic published by The Verge. https://www.youtube.com/watch?v=sQZfHnS3cG0&t=1s
In 1938, French avant-garde playwright Antonin Artaud described the illusory nature of characters and objects in the theatre as "la réalité virtuelle" in a collection of essays, Le Théâtre et son double. The English translation of this book, published in 1958 as The Theater and its Double, is the earliest published use of the term "virtual reality". The term "artificial reality", coined by Myron Krueger, has been in use since the 1970s. The term "virtual reality" was first used in a science fiction context in The Judas Mandala, a 1982 novel by Damien Broderick. https://www.youtube.com/watch?v=v55zEjX-lRE&t=1s
The newest breed of mobile headsets can also be considered "tethered," because instead of inserting your phone into the headset itself, you physically connect your phone with a USB-C cable. Qualcomm has been emphasizing the VR and augmented reality capabilities of its Snapdragon 855 processor, and is promoting a new ecosystem of XR viewers (including both AR and VR devices). These use the aforementioned USB-C connection to run all processing from a smartphone, while keeping the display technology built separately into the VR headset or AR glasses. https://www.youtube.com/watch?v=jLtcPTm5dTg&t=1s
